COMBINATION rLow AND YPULVERIZER.

To all whom it may concern:

- Be it known that :I, .EDWARD -MATTHIEN- SEN, a'citizen ofthe United States, residing at Minneapolis, in the county of Hennepin and State ofMinnes'ota, have invented certain new anduseful Improvements in Combination Flows and Pulverizers, of which the following is a specification;

My invention relates to plows and the object is to, provide'a machine of such construction that it will plow the ground by digging and lifting the dirt upon anelevator from the'upper .end of which it is as a rear support for the machine. 'The construction is clearly illustrated in the accompanying drawings, in which:

Figure l is a side elevation of the machine with a few portions broken away. Fig. 2 is a top view of the machine shown in Fig. ,1; Fig.3 is anenlarged sectional detail view on the'line 3+3 in Fig. 1. Fig.

Referring to the .drawlngs by reference numerals, 1 designates a main frame which is supported at itsfront end by two wheels 21 and at its rear end by a drum or roller 3. The wheels 2 are secured upon an axle 4 which is pivotally-mounted to a brace 5at a'point 6 to oneside of the center of the frame so that neither of the -Wheels 2 will run in plowed ground. Secured to the axle 4 is a tongue or pole 7 to which can be hitched horses for pulling the machine.

Upon the front portion of the machine is secured a gas engine 8 adapted to transmit power through a shaft 9, bevel gears 10,11, shaft 12, spur gears 13 and 14 and-thus operate the elevator. The elevator consists of two heavy sheet metal walls 15 having near their upper ends journal members 16 adapt ed to rotate in bearings 17 secured to the underside of the main frame 1. Within the journal members 16 is rotatably mounted a v shaft 18 having secured upon one end the provided with angular digging extensions or shovels 21. Theapron is wide enough to fill completely between the two' elevator walls 15, and is stretched over the wheels 19 v Specification of Letters Patent.

at the upper end and over a roller 22, jour-.

naled in the side walls, at its lower end. Said roller 22 (see Fig. 1), because of the fact thatit is comparatively small in diame ter, isprovided with several fiat surfaces so as to moreefficiently engage the links of the apron. Two strips 23 preferably of angle iron are secured upon the inner sides of the elevator walls for the purpose of strengthening the same and also for supporting the upper run of the carrier apron. On each shovel or angle portion 21 of the apron are detachably secured a series of pointed digglng members 24 secured by means of screws or bolts 25 (see Fig. 4).

The lower end of the elevator is raised or lowered as desired by means of a hand lever 26 (see Figs. 1 and 2) having a dog 27 adapted to engage notches in a toothed sector 28 on which the lever is pivoted at v29. The lower endof the lever 26 is pivotally connected to a bail 30 secured at its ends near the lower end of the elevator walls.

The rear end of the frame 1, and thus also the upper end of the elevator, can be raised or lowered by hand levers 31 having hand actuated dogs 32 adapted to engage notches.

shown in Fig. 1) is dug up bythe shovels 21 and diggers 24, and is carried up to the top of the elevator where it is dropped again thus loosening and pulverizing it. The roller 3, which it will be noticed is wider than the elevator, then immediately rolls down the dirt again thus leaving a desired smooth surface. It is apparent that the dirt thus dug up and handled will be more thoroughly mixed than in the old way of plowing where the dirt is merely turned over. Another advantage of plowing with this method is that because of the diggers 24 the plowed bottom is not left smooth but is corrugated, which is especially desirable because on hillsides the water is then more easily retained. A particular featureof the construction in this machine 7 is shown in Fig. 3. The elevator is piv- V otally mounted to swing on the same center as the shaft 18 but'is not trunnioned on it. The journal members 16 have thelr bearing inthe boxes or bearings 17, and the shaft '18 is journaled within the members 16.

Thus the pressure against the elevator, caused by the forward movement of the machine'against the ground, will not tend to bind against the driven shaft 1 8, and the same'will only have to overcome theresistance of the diggers on the carrier."

It is understoodthat the above combinations can be used in a variety of forms and structures if within the scope of the appended claims.

-Having nowtherefore fully shown and described my invention, what I claim to be new and desire to protect by Letters Patent is: r w

1. A machine of the class described con sisting of a main frame adapted to be drawn, two front wheels and a rear drum supporting :said frame, a forwardly inclined elevator mounted within saidframe forward of" said drum, an endless carrier mounted in said elevator and adapted to be" driven by an engine on the frame, spaced shovels on said carrier adaptedto dig and carry dirt up the elevator and drop the same in front of said drum.

2. A machine of'the class described consisting of a mainframe adapted to be drawn, an elevator pivotally mounted upon said frame, an endless carrier'and spaced shovels secured upon the same mounted within the elevator, an engine securedupon' the'frame, operative connection between the engine and saidcarrier, a drum supporting the rear end of the frame and the same being wider than the width of the carrier, two

said elevator andmeans for actuating the same, spaced shovels secured upon said carrier adapted to dig, elevate and then release dirt assaidelevator is being actuated and the machine is moving forward, wheels supporting the front end of the frame, a transversely positioned drum supporting the rear end of the frame and being wider than said elevator, said drum being adapted to roll down dirt as it is beingreleased from the elevator, vertical casing members extending downwardly from the sides of the rear end ofthe frame, bars slidably mounted withinsaid casing members, said drum being journaled at its ends in the'lower" ends of said bars, hand levers connected to said barsfor the purpose of lowering and raising the same. a

4.- Ainachine of'the class describedconsisting of a wheel supportedframe adapted to" be drawn, a longitudinally positioned inclined elevator comprising two side walls, upper and lower rollers journaled in said side walls, an endless'carrier havingspacedshovels thereon, stretched over said rollers, JOHTIlEtl members secured to said side walls and having their bearings 1n boxes secured to the main frame, a shaft journaled within; saidbearings and adapted to actuate said carrier; a source of power and operative connection between the same and said shaft.

In testimony whereof Iaflix mysignature.
